Hawkins County Sessions Judge J. Todd Ross served the dual role as juvenile judge during Boyd's 120-day suspension, which began Jan. 10.
A Supreme Court press release Monday stated that Boyd filed a petition for reinstatement to the practice of law, and the board found that the petition was satisfactory, and submitted an order of reinstatement.
Boyd also agreed to accept three years of probation and submit to additional training in the areas of ethics and/or management of his law practice.
A complaint was filed against Boyd in 2016 by the children of an elderly widow who suffers dementia and was seeking a claim from the will of her late husband.
The late husband has children from a previous marriage, and in September 2010, Boyd agreed to represent the widow by filing a petition for her late husband's elective share.
Over the course of the next five years, Boyd reportedly lied to the widow and her children on multiple occasions, stating that the petition for elective share had been filed and was progressing normally.
Boyd stated in his response that after he took over as "part-time" Hawkins County Juvenile Judge in 2011, the job consumed nearly all of his professional time.
